Quick Answer
L-Citrulline Resistance Exercise Randomized Trial has evidence relevant to benefits, uncertainty, and practical interpretation, but conclusions should stay close to the cited sources. One representative finding is: Although generally considered safe, their combined use with high-intensity training may increase the risk of exertional rhabdomyolysis and secondary liver or kidney injury.
Key Takeaways
- 01Although generally considered safe, their combined use with high-intensity training may increase the risk of exertional rhabdomyolysis and secondary liver or kidney injury. [Chowaniec P (2026)]
- 02Laboratory evaluation revealed markedly elevated creatine kinase (>120,000 U/L) and increased aminotransferases (aspartate aminotransferase (AST) 1,275 U/L; alanine aminotransferase (ALT) 337 U/L), with preserved renal function (creatinine 1.0 mg/dL; estimated glomerular filtration rate (eGFR) 108 mL/min/1.73 m²). [Chowaniec P (2026)]
- 03Creatine and β-alanine enhance exercise capacity through complementary mechanisms involving adenosine triphosphate (ATP) resynthesis and intracellular buffering, potentially enabling greater training loads and increasing risk of muscle injury. [Chowaniec P (2026)]
- 04Dietary supplements such as creatine, β-alanine, citrulline malate (CM), phosphatidic acid (PA), and β-ecdysterone are widely used to enhance exercise performance and muscle hypertrophy. [Chowaniec P (2026)]

Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording.
